A CAGED-based fretboard trainer built on triads. Practice through CAGED positions, smooth voice leading and real chord progressions until finding the closest inversion becomes automatic — free, no sign-up, every quality in every key.
Stop being limited to open chords. Every CAGED shape is the same chord relocated to a different fret region — a fretboard visualization tool for seeing where triads live across the neck. Learn all five shapes and the whole neck becomes playable, not just one position.
Forget bulky barre chords that kill your hand. Triads are just three chord tones on three strings—tiny, moveable, efficient. Drill recognition (see a triad, name it) and recall (hear a name, find it) across every inversion until theory clicks. No confusion, just muscle memory.
This is voice leading for guitar: stay in one fret region and move between three voicings using the smallest possible hand movement. Drill real chord progressions until your fingers find the closest inversion without thinking — practical rhythm guitar practice, not random chord jumps.
Triads are the entry point, not the whole story. Underneath, this is a CAGED-based fretboard-training system — recognition and recall drills, voice-leading practice between positions, and progression-based rhythm guitar practice, all built around the same idea: navigating the neck matters more than memorizing shapes.
Yes. There's a built-in tutorial that gets you going in under a minute, plus dedicated learn pages covering triads, the CAGED system, and inversions. The modes range from single-triad drills in one key all the way to full CAGED recognition with random chord changes — you'll naturally move toward harder modes as things start clicking.
Not much. You don't need to read sheet music or know chord theory inside out. That said, if you have even a basic feel for intervals — knowing a major third sounds one way and a minor third another — that awareness will speed things up noticeably. It's not a requirement to start, but something worth building alongside your practice.
Two core drill modes: Recognition (you see a triad on the fretboard and name it) and Recall (you're given a chord name and find it). On top of that there's Flow mode — a hands-free loop that plays triads at a tempo you set, so you can practice while playing along on your instrument. Within each mode you can narrow it down to a single chord type, one CAGED shape, specific string sets, or open everything up to all 12 keys and all four qualities at once.
CAGED is woven into everything, not an afterthought. Triads and CAGED shapes come from the same root — every CAGED shape naturally contains a set of triads, and understanding that connection is what actually unlocks the neck. Think of it like learning pentatonic scales without pentatonic boxes: you could technically do it, but you'd be navigating blind. The app constantly shows you which CAGED shape a voicing belongs to, so the two systems reinforce each other from day one.
All four: major, minor, augmented, and diminished. You can drill each quality in isolation or mix them all together — every quality, across all 12 keys, on all four string sets.
Yes. Flow mode lets you set a tempo and loop through triads hands-free — the idea is you listen and play along at the same time. That alone is a solid workout even if you know your shapes. Turn on chord changes and it steps up considerably: the app cycles through a progression and you track the changes in real time while playing. The right tempo, chord changes, all positions — that combination is something you can keep pushing for a long time.
Progression lock mode dedicates each session to a specific chord movement — I–IV, I–V, I–IV–V, and others. The trainer picks close-voiced triads so you're learning transitions that actually make sense on the neck, not random jumps. It's the most practical mode for anyone working on rhythm guitar or learning to comp.
Yes. Progression lock isn't limited to generic I–IV–V drilling — it covers movements pulled from Rock, Pop, Jazz, Blues and more, so you're not just memorizing a chord chart, you're feeling how each genre actually moves. A blues turnaround resolves differently than a jazz ii–V–I, even inside the same fret region, and that difference is exactly what trains your ear and hand for smooth voice leading. Switch styles and the trainer keeps picking the closest inversion for you, every time.
